Additions

• IDL Maps are now supported by opendds_idl. (PR #4999)
  • We would like to thank tmayoff for contributing much of the work needed for this.
  • Usage example:

    @nested
    struct Item {
      string desc_name;
      uint32 count;
    };
    
    @topic
    struct Inventory {
      map<string, Item> items;
    };
    

  • They map to C++ std::map in both the classic IDL-to-C++ and IDL-to-C++11 mappings.
  • See IDL Compliance for known limitations.
• RtpsRelay
  • Output from RtpsRelay -LogRelayStatistics / RtpsRelay -PublishRelayStatistics includes extended RtpsRelay statistics (PR #4972, PR #5006)
  • Output from RtpsRelay -LogRelayStatistics / RtpsRelay -PublishRelayStatistics includes internal OpenDDS statistics (PR #5000, PR #5006, PR #4990, PR #5023)
  • RtpsRelay no longer needs to store and replay SPDP messages (PR #5017, PR #5020)
  • The OpenDDSInternalThread built-in topic has additional detail fields which may be populated by internal threads. (PR #5026)
    • The RtpsRelay's event handling threads make use of this feature.
  • RtpsRelay expiration/deactivation is now done by separate timer events instead of during input handling (PR #5032)
  • RtpsRelay -DrainInterval can drain clients to implement a controlled shutdown (PR #5063)
• Added [rtps_discovery] IgnoredSpdpUserTags. (PR #5046)
• When DDS Security is configured to require authentication and an incoming SPDP message has a different Identity CA, authentication is not attempted. (PR #5046)

Platform Support and Dependencies

  • Updated ACE 6/TAO 2 from 6.5.21 to 6.5.22.
  • Updated ACE 8/TAO 4 from 8.0.3 to 8.0.4.
• CMake
  • opendds_target_sources now has a FOLDER argument which sets the CMake FOLDER property on generated targets. (PR #5009)
  • Fixed accidental use of RapidJSON's CMakeLists.txt file when building OpenDDS with CMake. (PR #5054)
    This caused issues such as forcing the CMAKE_CXX_STANDARD to C++11 and breaking the ACE C++ standard detection code.
  • Fixed configure issue with Xerces from vcpkg when building OpenDDS with CMake. (PR #5054)
• The configure script detects the C++ standard supported by the Android NDK compiler (PR #5057, PR #5052)

Additions

• Added support for the @optional IDL annotation for the IDL-to-C++11 mapping. @optional maps to either std::optional or a similar custom implementation in the generated code. (PR #4364)
• Implemented the create_sample, create_sample_rc, create_dynamic_sample, and create_dynamic_sample_rc methods on TypeSupport to convert samples to and from DynamicData. (PR #4373)
  • Also documented the existing DynamicDataAdapter class for wrapping IDL-generated types in a DynamicData.
  • See DynamicData and IDL-Generated Types for details.
• Samples from DynamicDataReaders can be modified and passed to DynamicDataWriters. (PR #4609)
• Added config properties to give more control over what UDP ports RTPS uses: (PR #4655)
  • For RTPS Discovery:
    • Added [rtps_discovery] SedpPortMode=probe, which will use ports similar to how the RTPS specification defines them.
      This uses the existing port parameter properties for SPDP and a new one, [rtps_discovery] DY.
    • Added [rtps_discovery] SpdpPortMode as an alias to the now deprecated [rtps_discovery] SpdpRequestRandomPort.
    • Added [rtps_discovery] SpdpMulticastAddress, [rtps_discovery] Ipv6SpdpMulticastAddress, [rtps_discovery] SedpMulticastAddress, and [rtps_discovery] Ipv6SedpMulticastAddress to set the multicast addresses and ports separately on SPDP and SEDP.
    • See here for the full overview of port usage.
  • For RTPS/UDP Transport:
    • Added [transport] PortMode=probe (rtps_udp), which will use ports exactly as the RTPS specification defines them.
      This uses new port parameter properties: [transport] PB (rtps_udp), [transport] DG (rtps_udp), [transport] PG (rtps_udp), [transport] D2 (rtps_udp), and [transport] D3 (rtps_udp).
    • See here for the full overview of port usage.
  • All ports calculated using port parameter properties now warn if they overflow the 16 bit integer.
  • [rtps_discovery] SedpPortMode=probe and [transport] PortMode=probe (rtps_udp) might make config template customizations unnecessary.
• Added dds/OpenDDSConfigWrapper.h and dds/OpenDDSConfigWrapper.idl. (PR #4659)
  • These files will provide defaults for various configuration macros.
  • These files should be included in preference to dds/OpenDDSConfig.h
• Added a new data member, monotonic_timestamp to the InternalThreadBuiltInTopic IDL struct. (PR #4677)
  • monotonic_timestamp is the time of the sample was written (time of last update of this instance) on the monotonic clock.
  • On systems that don't support a monotonic clock, this will be the same value as the corresponding SampleInfo's source_timestamp.
• The ParticipantLocation BIT instance is now published before participant discovery completes. (PR #4693)
  • Applications can use ParticipantLocation to get notified that discovery is in progress. The spec-defined Participant BIT won't be published until participant discovery is complete.
• The Info Destination submessage is now used if present in incoming SPDP messages (PR #4710)
• The ParticipantLocation BIT has a new data member: the SPDP user tag of the peer (0 if none present) (PR #4711)
  • Also added the SPDP user tag to outbound messages which are directed to a specific destination
• [rtps_discovery] ResendPeriod now accepts fractions of a second. (PR #4712)
• OpenDDS now sends pre-emptive (pre-association) acknacks in a form that RTI Connext understands. (PR #4735)
• Pre-association acknacks now fall off like heartbeats. (PR #4735)

Platform Support and Dependencies

• ACE/TAO
  • Added support for building with ACE 8.0.0 / TAO 4.0.0.
  • Updated ACE 6/TAO 2 from 6.5.20 to 6.5.21.
• CMake
  • Allow using the ACE/TAO master branch which now requires C++17. (PR #4618)
• Building with CMake
  • Visual Studio now defaults to using at least C++11 with ACE 6/TAO 2 instead of C++03. (PR #4618)
  • Fixed configure error when using OPENDDS_JUST_BUILD_HOST_TOOLS with CMake <3.28. (PR #4646)

Removals

• Removed OPENDDS_IGNORE_OPENDDSCONFIG_H_FILE macro. (PR #4687)
  • Users manually configuring a build will need to create dds/OpenDDSConfig.h which may be empty.

Fixes

• When DCPSThreadStatusInterval is enabled, threads that run the ACE Reactor now use timers instead of a time-limited select() system call to update the InternalThreadBuiltInTopic. (PR #4677)
  • This allows the InternalThreadBuiltInTopic to be updated accurately on systems that suspend/resume and are configured for boottime timers.
• [rtps_discovery] MaxSpdpSequenceMsgResetChecks is recognized again. (PR #4696)
• RtpsRelay: Recognize clients that are using different IP addresses for SPDP and SEDP. (PR #4718)
• Fixed memory leak of remote locators in the RTPS/UDP transport. (PR #4731)

Documentation

• Documented RtpsRelay -LogHttp, RtpsRelay -AdmissionControlQueueSize, and RtpsRelay -AdmissionControlQueueDuration. (PR #4699)
• Documented [SPDP](https://opendds.read...
